SPECIFICATION forming part of Letters Patei1`t`No. 494,317, dated March28, 1893.

Application filed October 25, 1892. Serial 110.449,913. (No model.)

To a/ZZ whom it may concern:

Be it known that I, PAUL BLANCHARD, a citizen of the United States,residing at Arnaudville, in the parish of St. Landry and State ofLouisiana, have invented a new and useful Road-Scraper, dto., of whichthe following is a specification.

My invention relates to improvements in road-Scrapers; and the object inView is to provide an extremely cheap and simple construction ofscraper, adapted to scrape and level roads, fields, clean out and formditches, and to be conveniently transported to and from the eld ofopera-tion.

Various other objects and advantages will hereinafter appear in thefollowing description, and the novel features of the invention will bespecifically pointed out in the claims.

Referring to the drawings-Figure 1 is a perspective View of aroad-scraper constructed in accordance with my invention. Fig. 2 is arear elevation thereof. Fig. 3 is a longitudinal sectional View.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In practicing my invention, I employ a suitable transversescraping-blade 1, the same being formed of sufficiently 4heavysheet-metal,

having its lower edge beveled, to form a scrap' ing-edge, and itsopposite ends preferablyforwardly bent at right-angles to its main orbody-p0rtion, forming end-wings 2. An inverted U-shaped clip 7, passestransversely through the blade near its upper edge, and its terminalslikewise pass upwardly through a centrally located draft-tongue, 4, saidterminals being nutted thereabove, as shown. A pair of handles 5, havetheir lower ends secured to the opposite sides of the tongue, inelineupwardly and rearwardly therefrom, are connected by suitable rungs, andbraced by a pair of brace-straps 6, whose lower ends are secured to theopposite sides of the tongue. The blade and tongue are further connectedby means of a pair of converging hounds 3, whose rear ends are passedthrough perforations in the blade in rear of which they are headed, andwhose front ends are securely bolted to the aforesaid tongue.

A divided standard 8, rises from the tongue in rear of the point ofconnection between the handles and tongue, and in the same is pivoted orfulcrumed as at 9, the lower bent or.

curved end 10, of a hand-lever, ll, whose upper end extends up betweenthe handles, and may be connected with either of a pair of hooks, 12,located upon the upper and lower rungs of the handles.

Near the ends and at the rear sides of the scraper-blade are pairs ofvertically opposite keepers 13, and in each pair there are located thespindleorshank-portionsliofsmallcasterwheels l5. These spindle orshank-portions are free to reciprocate vertically within the keepers,and are connected by a longitudinal bar 1 6, whose central portion isdepressed or offset, at 17, and is straddled by a yoke 1S, that alsoembraces or straddles the rear end of the tongue, and is pivotallyconnected to the rear extremity of the lower bent end of the hand-leverheretofore described, as shown at 19. Thus it will be apparent that byraising the hand-lever or throwing the same forward at its free end,itsrear end serves to elevate the yoke, the connecting-bar, and the castersand their Shanks, so that the blade is lowered into contact withY theground. By engaging the lover under the front hook of the pair, theparts are securely locked in this position, and the machine is incondition to be employed as an ordinary road-scraper, leveler, or forcleaning out ditches. By a reversal of the lever, that is, throwing thesame tothe rear and engaging the lever with the rear or upperhook,whereby it becomes locked, the yoke is forced down, as are also theconnecting-bar and the casters, the wheels being forced into contactwith the ground and the machine elevated so that the blade is out ofcontact therewith. 'lhe machine may now be readily transported to orfrom the field of operation, or if desired, and when leveling soft soilsuch may be accomplished, the blade being held sufciently above thesurface of the soil to enable it to engage with any hillocks.

From the foregoing description in connection with the accompanyingdrawings, it will be seen that I have provided an extremely cheap andsimple road scraper, one well adapted to perform all the usual functionsof such lever having a lower rearwardly bend end fulcrumed on thedraft-tongue, a yoke connecting the lever at its rear extremity with theconnecting bar, and means for securing the lever in either a rearward 0rforward position, substantally as specified.

2. In a machine of the class described, the combination with a centraldraft-tongue, a transverse scraping-blade connected therewith, andprovided upon its rear side with keepers, a pair of` diverging handlessecured to and rising from the tongue, and upper and lower rungsconnecting the handles, casteri wheels having their shanks mounted inthe keepers, a standard upon the tongue,a handd lever having a lowerrearwardly curved end fulcru med in the standard, a yoke connected tothe rear end of the lever, a connecting bar between the yoke andcaster-Shanks, the saine being connected with the lower end of the yoke,and hooks located upon the upper and lower rungs and adapted forconnecting with the lever, substantially as specified.

In testimony thatI claim the foregoing as my own I have hereto aixed mysignature in the presence of two witnesses.

PAUL BLANCHARD.
